Shōshō Akatsuka, the younger sibling of Taisho, debuted in the initial anime adaptation of the series and persists as a recurring character in later adaptations. Consistently portrayed as a toddler who speaks fluently yet cannot walk independently, he relies on riding the family cat Dora for mobility. His primary narrative role involves functioning as Taisho's constant companion and sidekick, particularly in scenarios lacking other children. The name "Shōshō" operates solely as a nickname or title, translating to "Major General"—a direct nod to his older brother's designation as "The General" (Taisho). Though the 1988 anime adaptation revealed Taisho's full name as Daisaku Akatsuka, Shōshō's formal given name remains undisclosed across all documented media. His character exhibits no substantial evolution, expanded backstory, or altered core traits—such as his dependence on Dora and his function as Taisho's moral compass—throughout television series, films, or other official productions.
